  2. The Pleiades seen from Kelvedon Common in Essex - 22nd August 2025. 8 x 2 minute exposures at 800 ISO11 x dark frames11 x flat frames24 x bias/offset framesGuided with PHDStacked and calibrated in Maxim DLPost processed in Maxim DL, Nebulosity, and Photoshop
  3. Hi all, heres my attempt at M45 this year. Exposure details: 60x210 seconds, f2.8, ISO 800, calibration frames, 200mm With just under 3 hours 30 minutes this has fallen far from how i wanted it to be. I planned on getting 10 hours! But with cloud forecast all week i'll settle with this till later in the year. I shot using the lens wide open and using the 3rd point focusing method, hoping to have enough light grasp to pick up some of that faint dust in the area. I picked up 7 hours over 2 nights and thats when problems started. My first imaging session was the first time i used my new dew heater, i focused and then turned the heater on which shifted the focus i think, leaving me with over 3 hours of un-stackable data! This image is made up of data from the second session, you can see that the stars appear to trail and i wanted to ask if anyone using this focusing method has ever been left with stars like those in the image? They appear to streak a little bit and look as if they are rotating around a center point. I have spoken to one other person who has experienced this. Because i have recently started using Backyard EOS, im not aware how to set up the live view so you have the 4 intersecting lines (if its even possible) so when focusing i roughly guessed where the intersecting lines would be. If i didnt have the star in the right place, could it have caused the stars to appear the way they do? Anyway, heres the image. Clear skies!
  4. Have been looking forward to imaging this one for the longest time! The fall weather recently sunk my Comet ISON ambitions over the last week but then the skies cleared last evening and an indian summer night rolled in with perfect seeing yes!22-300 second light exposures at ISO 800, 15 dark frames and 25 bias frames. Levels and curves in PS 5 and some final tweeking in Lightroom. Let me know what you think of the processing. Look up!

  6. My first go at imaging m45 shot using a vintage super takumar 135, f3.5 iso640 best 80%of 35 120second subs. The camera was mounted on a star adventurer and polar alignment was rough
  7. kit- super-tak 35/135, 1200d unmodded, Heq5 . taken from my obsyroom open window. seeing was very good uptill 10.30, then thin cloud arrived as soon as Orion cleared the horizon, but most of it staxed out.

  8. I forgot to share this one last month. Between travel for business and brutally cold weather closing down my nearby imaging location in the mountains I have not had time to image this year. This was taken at the beginning of December and contains a very busy wide field splitting the constellations Taurus and Perseus. The better known DSO's are M45 the Pleiades reflection nebula and NGC 1499 the California emission nebula. The center of the image contains a dark nebula which I am not familiar with and the rest of the region is quite heavily laden in ISM interstellar medium dust. This image was taken with my unmodded T3i Information about this image camera: unmodded T3i ISO:1600 Exposures: 102 x 100s Darks: 5 ugh, mishap Bias:450 frame master Flats:35 Lens:SMC Pentax M* 50mm F1.7 stopped to F4 SQM: 21.1 Seeing: 3/5 Transparency:3/5 Calibrated and partially processed in Pixinsight and finished off in Photoshop CC 2017.

  9. Hi everyone, was out last night till 2.00 ish brrrrr!!!, my first serious attempt at Pleiades on my un-modded 600D & no filters Canon 55-250mm @ f5.6 (would Baader Blue filter help bring out more detail ? ), fighting against all night dew was a headache but that's why i bought the wife a nice hair dryer for , final shot is 3 subs @ 1600 / 20 secs, 8 subs @ 1600 / 60 secs, 10 dark frames & 5 flat frames (i keep forgetting to do them), processed in DSS & CS6. My 'main' stars seem blown, i used levels + curves but not sure exactly what to adjust to reduce the bright whites but keep background dark & keep blues in tact ? I'm please how it's come out & hope you like it too.

    Taken using Canon 100D with a 300mm lens mounted on Skywatcher Star Adventurer. Single 2 minute exposure - too much moon light and LP to allow the necessary settings to bring out the nebulosity.

  12. Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) .........

  13. Hi, First post on SGL so hello everyone and thanks for all your posts. They have helped me greatly to hit the ground running with my new hobby! This is my first ever DS image taken on 4th night out with my scope. I spent the first 3 sessions practising setting up, polar aligning and imaging moon etc. Last night I nearly never ventured out because of the moon and cloudy forecast but so glad I did! When aligning my finderscope I stumbled upon M45 and decided to give it a bash. Managed around 40subs before clouds rolled in and moon came up but very chuffed with my first result! Criticisms and advice more than welcome Image + Processing: M45 Pleiades 01/04/18, from back garden in southside of Glasgow ~40 x 30sec subs 10 Darks DSS + Photoshop (Messed with curves, levels and used Gradient Xterminator) Equipment: Skywatcher 200PDS HEQ5Pro mount CanonEOS1200d
  14. Had some nice clear skies last weekend, so I simply had to take advantage of them, even though the temps dropped to -4 on the Saturday night! Thankfully i was able to just move the car a few metres and use the frost-free ground underneath to set up. And boy, what a god send Team Viewer is! I Once i was all set up, i was able to monitor it all from inside the house. Most of the neighbour's had selfishly decided to light fires, how inconsiderate of them, lol. It was quite annoying though i have to say, seeing all the smoke at times billowing across my FOV! Thankfully i stayed up late though, so i outlasted most of them It was easily the most productive 2 nights I've had so far. The skies were completely clear all night long on both nights. In the end i managed 11 hrs worth of exposure in total over the 2 nights. I still need to process the Soul Nebula subs (Ha and OIII), hope to get to that later this week, but for now here's the other object i was shooting, good old M45. So this is 2 hrs 40 mins (16 x 600s) using the Nikon D5300a and an IDAS-D1 filter. 30 Flats, 50 Bias, with aggressive dithering. Captured with Sequence Generator Pro, stacked in Astro Pixel Processor, and processed in Photoshop. I may have gone too far with the processing (i tend to do that), what do you guys think? I had an earlier version which was sooooo much smoother, but it was seriously lacking in visible nebulosity, so i kept going! Plus, i wanted to try and eek out some of the surrounding dust, which i just managed to get. I might end up reducing it by 50% in size, due to the noise, haven't decided yet though. C&C welcome as always of course! The last RGB image i did was a brief go at M42 about a year ago, and that was also taken from home using the same filter. I had forgotten just how hard RGB processing is when not captured from a dark sky! ps - I've also added a version below with some funky diffraction spikes. Just for fun of course! Although i actually don't mind them
  15. Had scope out last night but seeing was rubbish due to moisture so I decided to piggyback my dSLR & capture some widefield shots. All images are taken at 14mm on my 4/3 dSLR, equiv to 28mm full frame. Pleiades or M45 by 1CM69, on Flickr M31 Widefield by 1CM69, on Flickr Orion widefield showing M42 nebula by 1CM69, on Flickr Thanks for looking.
  16. It rained yesterday, but it was mostly clear after midnight. I just used my binos after 12:30 and saw the Pleiades, all of Orion including M42, Auriga and some open clusters just to the south and east of it. Today was the first day I could see Orion, because I set up in my backyard and my row of townhomes blocks a lot the sky from northeast to southeast. M42 looked great in my 15 x 70 binos, although not as good as in my telescopes. I can make out the nebulosity very easily and could see 3 fairly bright stars in the nebula.

  18. Hi folks, The Pleiades were the subject I chose for "first light" when I got my imaging system up and running earlier in the year. I promised myself I would return to them in the autumn and here's the result, uncropped apart from a 48 pixel wide border but then downsized by a factor of four: The PleiadesI've linked to a larger (2048 x 2048 pixel) version which you can see by clicking the image. The 4096 x 4096 pixel original doesn't really add anything to the party in terms of extra resolution of the nebulosity. The subs used were 5 x 1,000 seconds blue and 5 x 200 seconds in each of red, green and blue using my Astrodon Tru-Image filters. As ever the 'scope was my TEC 140 and the camera an ML16803. Processing was a real challenge for me because the brightest stars were still well blown even on the 200 second subs. In the end I decided to do without any shorter exposures so I combined the 200 second RGB subs to get a colour image and combined the 200 and 1000 second blue subs using PI's HDRComposition tool to get a much deeper image of the reflection nebulosity while still controlling the size of the brightest stars. That image then had its stars removed and that's where the fun started as there was no way I could reliably clone out the brightest stars as they were so intimately bound with the illumination of the surrounding gas and dust. In the end I opted just to darken the very brightest stars as the whole purpose of the exercise was to try and prevent ringing during subsequent processing of the nebulosity and ringing is basically triggered by very sharp transitions in brightness. Anyway, the "no stars" image went back from Photoshop into PI where the tool of choice was LocalHistogramEqualisation. The original plus the LHE version were both processed further in Photoshop and then blended together and the result coloured using a Curves layer. The cleaned up and enhanced RGB image was then added as a screen layer which neatly added the stars back, including over-painting those problematic very bright ones, and also slightly modified the colours of part of the brightest areas of the nebulosity. Obviously there were lots of extra tweaks along the way but those were the headline steps. Quite an adventure and there's always a worry that the end result owes too much to the choices during post rather than reflecting (sic) what was actually there but I'm pleased with the result, especially as I wasn't expecting to see so much structure so distant from the Pleiades themselves. I hope you like the result. Bob.
  19. Hey folks, this is an attempt to image m45 and get the nebulosity of the "seven sisters". 20subs * 30sec on ISO 1600. enjoy, please free to comment and collaborate. theo

    M45 12-07-18

    From the album: Beginnings

  21. The Pleiades (M45). This is a shot I've been wanting to do for a long time. Previous attempts were unsatisfactory because my 127 Mak has too much focal length for this object and looked straight through it and using a camera lens made unattractive spokes around the stars caused by the iris of the lens. With the 150mm Newtonian scope the framing is great and plenty of nebulosity can be captured. Also the spikes caused by the secondary mirror spider add to the image. Not perfect perhaps but definitely the best attempt so far. 44 x 75 second exposures at 400 ISO (55 minutes integration time). 46 x dark frames 38 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  22. a play last night with Comet Lovejoy with a Canon 5D3 and 70-200mm f/2.8 lens while I was there I couldn't resist a pop at M45, the Seven Sisters
  23. Hello, Just got a new (secondhand) EOS 6D and decided that the area around Pleiades is very good test The first light was ruined by clouds (no surprises here) but last weekend was way better. Clear sky, no wind, temperature around -13C... So here is my image named "Ice and Fire" Very busy part of the sky between the famous Pleiades and California. Details in short: 6D (unmodified), 51x180s, ISO 2000, 10 sky flats, no darks, Samyang 85mm at f/4, EM-200, no guiding, APT dithering (direct mount control), APT, PI.
  24. Here's a single image of M45 from early this morning, plus a labelled version. Pleiades Cluster [part of] by 1CM69, on Flickr Pleiades Cluster [part of] Labelled by 1CM69, on Flickr Taken at prime focus on my Celestron CPC925 using a f/6.3 reducer with my Olympus E-510. Due to the 2x crop factor of my camera, the resulting focal length is equiv to 2960mm at full frame 35mm, hence my inability to capture the whole cluster in a single frame because of decreased FOV. Addition of star spikes in Photoshop.
  25. Hi folks, yarp - yet another re-process. I've come a long way from the original as I've learnt new processing skills. This is from the same data - I hope the result pleases. The Pleiades - M45Bob
